12V 18AH SLA Battery Replacement for John Deere 155C Lawn and Garden

Great Product for the Price , I was assisting my friend whom is an engineer to help build a great long range e-bike . I had bought several e-bike kits via Wal-mart . All you do is follow instructions and you have a Great E-bike . But the problem is the lithium Batteries are expensive and they never last as long as the manufacturer says they will last , and the distance Traveled is nothing as they are advertised . So This Battery is a Great Alternative . However in our case a small Trailer is used ,, to be pulled behind the e-bike . You can buy what ever E-bike motor kit you want or like . But in our Case we bought the standard 26 inch,, 1000 Watt E-bike Kit . And we bought 5 batteries of this Product . The 5 Batteries are used in series but are charged in parallel . This is nothing for engineers or Engineering Technicians to comprehend . I am only an engineering Technician , but I constantly build things for Engineers . Anyway the 5 batteries, gave really long running time , and the Deep recovery meant gaining the maximum use out of the battery . So we had over a thousand watts ready . A tiny trailer worked great, and with the weight of these batteries , with the tiny trailer is less than 75 Lbs . The weight factor is very important . We have instruments on board the tiny Trailer to monitor the performance . In our case , a 14 year old boy was the target for riding , he wanted more than one hour of riding on level terrain . Lithium Batteries are typically 500 dollars to provide proper performance . 5 of these batteries were less than 220 dollars . The Engineers son has been riding the E-bike for over a month now and is spoiled rotten with pleasure .
